side-by-side relation, with thelips IB on one section entering throughtheslots 9 on the other section, and then by rotating the sections relative to each other, to secure these in binding relation to A each other. Y

Suitable means isprovided for securing the sections against relative rotation in their adgjusted positions. In the form illustrated, this is accomplished by means of a key designated gen- ..erally at Il, shown in Figs. 6 andl '7, and which :key passes -through registering holes -l2 Yin the sections I. The key Il should be constructed of a suitable metal or other materialwhich can pass through the sections and then have the ends bend over flat on the sections, as shownin Fig. 6, to anchor these securely against relative rotation.

- Y' The parts 'may be turned with respect to each other while the bushing `5 is interposed therebetween, because the bushing is free of one section which latter is Ajournaled in the groove '6, al-

-though secured to the other by the pin or key 8, and notch 1, whereby the bushing will not interfere with the relative rotation of the sections and yet will be securely anchored to the sheave to rotate therewith upon the shaft or journal when the parts are assembledin Figs. 1 and 2.

It willbe obvious that the bushing may beremoved from the body sections merely by disconnecting the latter from each other upon removal of the key Il, and replaced by a new bushing. These parts then may be connectedv together ture that mayvbenianufactured at low cost.

Whilethe invention has been illustrated and described in one embodiment, it is recognized that l .variations and changes may be made therein without departing from the invention, Vexcept as specied in the claims.
